VEHICLE WHEEL.

T 0 all whom it may concern.

Be it known that I, SawAnn H. MAN- cnnsrnxf a citizen of the lzlnitedStates, and resident of Winsted, county of. Litchfield, State ofConnecticut, have invented certain Improvements in Vehicle the followingis a specifinew and useful Wheels, of which cation.

The aim of the present invention is to provide in combination with theordinary solid tired wheels ofan automobile truck or the like,pneumatically tired wheels of greater diameter than the solid tiredwheels, and means for detachably connecting the pneumatically tiredwheels to the solid tired ones. With this arrangement, the ordinarysolid tired wheels of a truck may be employed to carry the load when thetruck is loaded, thus saving the more expensive pneumatic tires fromexcessive wear, and when the truck is running light, the pneumaticallytired wheels may be quickly slipped in placeand connected to the solidtired wheels to support the truck and make the truck easier riding andsave it from rack and tear to which it would be subjected were itrunningon the solid tired wheels.

In the accompanying drawing,

Fig. 1 is a sectional view showing the auxiliary or pneumatically tiredwheel connected to the ordinary solid tired wheel of a truck.

Fi 2 is an outside view of the ring 26 which is connected to the solidtired wheel.

Fig.3 is an inside view of the auxiliary or pneumatically tired wheel.

eferring to the drawings in detail, a denotes generally the solid tiredwheel fixed to a driving axle or shaft 6. This wheel may be of anysuitable construction, that shown in the drawings being by way ofillustration only. 0 denotes enerally the auxiliary or pneumaticallytired wheel which is here shown as having a and a rim 12 carrying thepneumatic tire 13 which is or greater diameter than the solid tiredwheel a.

The cap it at 15 and the of the wheel a is threaded as hub 10 of theauxiliary wheel is recessed and threaded as at 17, so that it may bescrewed onto the cap 1%. Accidental unscrewing of the hub 10 from thecap 14 is prevented by one or more set screws 18 he outer end of the hub10 has a ortion of reduced diameter which is received by a centralopening in the disk or web 11. This Specification of Letters Patent.Application filed June 6, 1921.

web is clamped to hub 10, a web or disk 11,

having a web, a detachable hub Patented June 26, 11922. Serial noeraser.

the hub 10 by a recessed cap 21 surrounding the reduced portion 19 andhaving a threaded stud 22 screwed into a threaded axial recess oraperture 23 in the outer end of the hub 10. Fixed to the outer face ofthe felly of the solid tired wheel a, as bymeans of bolts 25,, is a ring26 having spaced openings 27 adapted to receive lugs 28 fixed to the rim12 of the pneumatically tired wheel.

It will be seen that with this arrangement, when it is desired to usethe auxiliary wheel c, as when the truck is running light on a returntrip, it is merely necessary to slip the auxiliary wheel in place withthe lugs 28 engaging in the openings 27 and reduced portion 19 of theauxiliary hub extending through the central opening in the web 11 andthen screw home the cap 21 to clamp the inner edge of the web betweenthe opposing abutments 29 and 30 provided on the hub 10 and cap 21respectively. To detach the auxiliary wheels so that the truck, whenloaded, may run on the solid tired ones, it is merely necessary tounscrew the cap 21 and slip the wheel from place without disconnectingthe hub 10 from the cap 1% of the wheel a.

It is of course obvious that my invention is susceptible ofvariousmodifications and changes which are'within the spirit of theinvention without departing from the scope of the following claims; forinstance, the ring 26 is shown as being in four parts but it may be ofmore or less parts than four;

also, the construction of the auxiliary wheel may be other than thatshown.

I claim as my invention '1; In combination with the usual solid tiredwheel of a vehicle having a hub, of a pneumatically tired wheel ofgreater diameter thansaid solid tired wheel and having a web, adetachable hub portion, quickly detachable means for clamping said webto said hub portion, means for detachably connecting said hub portion tothe hub of the usual wheel, and readily separable engaging means carriedby the rims of said wheels.

- 2. The combination with the usual vehicle wheel having a hub providedwith an exter- V of an auxiliary wheel rtion, quickly removable meansfor clamplngsaid web to said hub ortionysaid hub portion having aninternay threaded recess adapted to receive mid externally threaded cap,and

nally threaded cap,

I 10 iary wheel to the hub of means between said hub portion and capforpreventing unscrewing of said hub portion.

3. The combination with the usual vehicle wheel, of an auxiliary wheelrovided with a web, a hub havin a reduced end adapted to be received bytie aperture in said web and a screw cap fitting about said reduced endand clamping said web to said hub; means for connecting said hub of theauxilsaid usual wheel,

ting in said openings,
